Is parvovirus B19 infection upsurge in 2023–2024 associated with adverse pregnancy outcome?
Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 307-313, September 2025.ABSTRACT Objective A surge in parvovirus B19 infections has been reported in 2023–2024 across Europe and the USA, raising concerns about the associated perinatal risks. The aim of this study was to compare perinatal outcomes following maternal parvovirus B19 infection during the 2023–2024 period with those from a pre‐2023 cohort.

Haiyang yu huzhao海表面温度(sea surface temperature, SST)是影响海洋和气候变化的重要因素之一，准确预测SST的变化对于海洋生态环境、气象和航行等至关重要。传统的SST预测方法通常依赖于数值模式，但是其计算成本较高。该文基于深度学习模型(3D U-Net)，将SST、海表面高度异常(sea surface height anomalies, SSHA)以及海表面风(sea surface wind, SSW)作为输入变量成功构建了南海SST的快速化智能预报模型。结果表明，与卷积长短时记忆 ...

Infant Mental Health Journal: Infancy and Early Childhood, Volume 46, Issue 1, Page 59-69, January 2025.Abstract This study examined the links between maternal self‐criticism, maternal postpartum emotional distress (PPED), and maternal non‐hostility among Arab‐Bedouin mothers living in southern Israel. We proposed a moderated mediation model in which self‐criticism would be related to PPED, which, in turn would be related to maternal non‐hostility.

Dianci bileiqi, 2019 针对现阶段仅依靠探空资料和潜势预报无法精准地预测雷电高发地区的现状,提出了一种基于潜势预报和雷达回波特征的雷电预报方法。首先采用L1正则化法筛选雷电预报因子,然后对3 h的潜势预报模型进行BP神经网络训练;在此基础上,利用潜势预报结果和雷达回波特征进行二次训练,构建30 min的临近预报模型;最后运用一次典型的雷暴过程进行方法检验,结果表明当概率阈值超过0.4时,临近预报的TS评分明显高于潜势预报。该雷电预报方法在空间精度和时间频率上均有明显提升,对提高雷电预报的准确率具有重要的作用。
